"I do not think a 248 @ 050 cam would make 650 HP even with the best carb."

+2

Not enough cam for 650hp, at least based on the 455 builds I've done here in the 600-650hp level.

The last one I remember doing that made right at 650hp used CNC ported 330cfm E-heads, Victor intake, 2" spacer, HP 950 carb and 260/;260 @ .050" cam. Had a tad more compression too.........
